最外层的循环i<15这里就错了不是，
然后呢，你没有考虑到变量自身赋值给变量这个问题，（代码写的很暴力）

//用哈希表就会很方便和轻松
```cpp
#include <iostream>
#include <string.h>
#include <map>
using namespace std;
int main() {
char ps[300] = { 0 };
map<char, int> m;
cin >> ps;
int len = strlen(ps);
for (int i = 0; i < len; i+=5) {
if ('a'<=ps[i + 3]&&ps[i+3]<='c') {
m[ps[i]] = m[ps[i + 3]];
}
else {
m[ps[i]] = ps[i + 3] - '0';
}
}
cout << m['a'] << " ";
cout << m['b'] << " ";
cout << m['c'] << " ";
return 0;
}
```
